// rust_g.dm - DM API for rust_g extension library
//
// To configure, create a `rust_g.config.dm` and set what you care about from
// the following options:
//
// #define RUST_G "path/to/rust_g"
// Override the .dll/.so detection logic with a fixed path or with detection
// logic of your own.
//
// #define RUSTG_OVERRIDE_BUILTINS
// Enable replacement rust-g functions for certain builtins. Off by default.

// On Windows, looks in the standard places for `rust_g.dll`.
// On Linux, looks in `.`, `$LD_LIBRARY_PATH`, and `~/.byond/bin` for either of
// `librust_g.so` (preferred) or `rust_g` (old).
